Abstract
To clarify the incidence of stenotic lesions according to the coronary arterial diameter in the acute phase we investigated 190 patients with coronary arterial lesions who underwent an initial coronary angiogram CAG less than 100 days after the onset of Kawasaki disease The largest diameters of the major branches were measured in the initial CAGs The diameter of the large group was ≥80 mm that of the medium group was ≥60 mm but 80 mm and that of the small group was ≥40 mm but 60 mm There were 121 patients in the large group 85 in the medium group 77 in the small group We investigated the stenotic lesions in the followup CAGs and evaluated the incidence of stenotic lesions in each group by the Kaplan–Meier method The mean interval from the initial CAGs to the latest CAG was 97 months The incidence of stenosis at 5 10 and 15 years in the large group was 44 62 and 74 respectively In the medium group the corresponding values were 6 20 58 respectively None of the patients in the small group developed stenotic lesions Dilatation of more than 60 mm produces a high probability of irreversible change in the coronary arterial wall leading to subsequent stenotic lesions
